The vibrating force is produced by an electro-hydraulic device:
Without eccentric axle, bearings, motors etc.
Consumable element: standard hydraulic gaskets.
Independent vibration frequency and amplitude
Vibration strength variable within the established frequency
Vibration only during penetration and closing (approx. 1/ 3 of cycle)
The consolidation achieved is not lost during the withdrawal of the tines
Double sleeper without any operation or mechanical buffer
